GATE.

SPECIFICATION farming part of Letters Patent No. 322,352, dated July 14, 1885.

Application tiled November 12, 1884.

To aZZ whom it may concern:

Be it known that I, WILLIAM H. COX, of Virden, in the county of Macoupin and State of Illinois, have invented a new and useful Improvement in Gates; and I do hereby declare that the following is a full, clear, and exact description of the same.

My invention relates to gates of that class adapted to be operated from the carriage.

The invention is an improvement on the gate patented by me on the 6th day of November, 1883, No. 287,805, and while retaining the same general principle of operation the details of construction are materially modified, the object being to render the mechanism more simple and efficient than in the patent referred to.

In the following specification I have fully described my improvements, and specifically indicated in the claims what I consider to be of my invention.

In the drawings, Figure l represents a rear elevation of my gate, the post being shown in dotted lines. Fig. 2 is a central vertical section, through the supporting-post and operating mechanism. Fig. 3 is a view of the end` Where the operatingmechanism is placed, representing the parts in front elevation, thesupporting cog-wheel being removed. Fig. 4 represents a sect-ion on line m x of Fig. 2. Fig. 5 is a view of the gear c', looking from the front. Fig. 6 is a detail section of the main supporting-wheel and track.

rIhe gate I have marked A,which may be of suitable construction. In the present form I have shown the ordinary slatted gate provided with a cap-piece. This cap-plate projects beyond the top rail, and in the angle I screw or bolt a cogged track, l,which is preferably cast in sections of two feet, more or less.

The gate is supported by a'cogged Wheel, A, which is on a shaft, c, supported in suitable bearings in a post, B', this shaft being capable of being revolved with the wheel. The wheel A is supported on the outer end of this shaft, and has cogged teeth on its inner surface adapted to the teeth on the track of the gate. These teeth do not extend to the outer periphery of the wheel, but terminate Within a short distance of the edge, so that the periphery of this wheel may bear directly on the gate-track,

(No model.)

and thus assist in the movement of the same,

a space, 2, being left between the teeth of the track and the rear wall of the angle-iron for this purpose.

The post B has an arm, B2, projecting from 3, is formed at the bottom of the post to assist v in supporting and guiding the gate, and, if desired, an antifriction roller may be used, also.

The wheel A, and through it the gate, derives motion as follows: A slotted plate or bar, D, is provided, having an upward extension, 4, for the connection of the operatinghandles, the slotted portion straddling the shaft a and the part 4L working in a guide, 5, on the upper part of the post. This plate D is in the shape of a rectangle,with a rectangular slot or opening in its center. The arms 6 7 on the right and left of the slot have rack-teeth raised above the level of the plate, the teeth projecting inwardly from the outer edge and alternately arranged, the teeth on spullen to the hub ofthe Wheel A is@ disk,

b, which is adapted to a gear-wheel, c`,on the said hub, and arranged beneath the plate D next the post. The interior of the gear c is recessed and is provided with a pawl, 8, and

spring, the pawl being adapted to engage with f a ratchet-wheel, d, secured to the disk b, the recess in the gear c being sufficient to receive it without crowding. The disk b entirely covers the recess and makes a smooth cover for the gear-wheel. The teeth on this gear engage with the rack-bar on the side of the arm 7.

Above the plate D is a disk and gear wheel, b c', in all respects similar to the one just described, the disk being splined to the hub of the wheel A, and carrying a ratchet-wheel adapted to operate withV thepawl within the gear c', and the gear engages with the rack` bar on the arm 6 in-certain movements of the` plate D, as hereinafter described.

It will be seen from the above that the gear c will turn freely in one direction when operated by the teeth of the rack of the arm 7; but when turned in the opposite direction the pawl will engage with the ratchet-wheel on the disk I) and will turn the wheel A and accordingly move the gate. The gear c' acts in a precisely similar manner when in engagement with the rack on its side, and turns the wheel A and gate in a direction opposite to the movement given by the gear c.

In order to provide for shifting the plate or frame D, so as to throw one or the other of the racks thereon into connection with the gear-wheels c or c', I use a shifting-lever, E, which is pivoted to the post at about its center, as shown. This lever passes below the plate D, but has turned-up iianges in its up- A per end,which enter theslotted portion of the plate D and rest against the wall of the slot. By means of this lever motion communicated through its lower end will throw the plate or frame D to one side or the other, so as to engage the gear c or c', as desired. In order to make this shifting automatic, so as to change at the end of one movement of the gate, whether the gate be open or closed, I provide the following devices: rIhe end of the lever E is bifurcated or pronged, as shown, and the parts thereof pass upon each side ol' a stud, 9, iixed inthe position shown. Upon this stud I pivot i a shifting cam-plate, G, which is constructed,

as shown, with curved sides approximately Wedge-shaped, enlarging toward its upper end. This shifting plate has lockingnotches e in the corners, which are adapted to pins f in the ends of the prongs of the lever E. As the shifting plate G is moved to one side the curved edge bears upon one ot' the pins f, and by reason of its wedge shape pushes the end ofthe lever E to one side until the pin falls into the locking-notch e, where it is held until the opening or closing ot' the gate is completed. This shifting ofthe lower end of E oi' course throws the plate or frame D to one side and places the rack on one side in engagement with the gear adapted thereto.

Pivoted to the same stud and resting upon the cam-plate G is a weighted lever, F, which is ofthe shape shown, carrying a weight, 10, upon its upper end and having a limited movement on the plate G between pins g g, set in each corner of the said cam-plate. The gate is provided at each end with a strip or projection, K, and the movement of the gate is between these projections. As the gate is being moved from one position to another, as it nears the end of its movement one of the projections comes in contact with the weight 10 of the lever, and as the movement continues the lever is moved in the same direction as the gate until it passes the vertical center of the pivotal point, whence it falls by gravity to the other side against the pin g of the cam-plate, which causes that plate to shift to the same side, which in turn bears against the pin p ofthe lever E, moving it to one side into the locking-notch e, this movement push.- ing the plate D to one side and connecting the rack and gear on the side opposite to that which had been previously engaged.

The extended portion of the plate D is provided with ears, to which are connected levers L L, and ordinary hand-cords are attached to these levers, as in my patent aforesaid.

The operation of the gate is as follows: Supposing the gate to be closed and the operator upon the side of the gate facing the wheel A. The gate being shut, the weighted lever has fallen over to the right-hand side. Apull on the cord draws up the Yplate D, the rack on the right hand engaging with the gear-wheel c. This opens the gate. Just before the gate has completed its movement in this direction the projection K on the front of the gate strikes the lever F, as described, throwing it to the opposite side, shifting the plate D through the lever E, and throwing the lefthand rack in gear with the wheel c. It will thus be seen that the rack and gear upon one side always opens the gate, and the opposite rack and gear closes it, without regard to which of the levers L are operated.

Any suitable stop at the ends receives the impact of the gate.

The racks on the plate D, when at rest, drop down so low that rack and wheel are not in gear, thus permitting the gate to be pushed backward or forward by hand freely.

Having thus described my invention, what I claim is- 1. A suspended gate resting upon a cogged wheel, a supporting-shaft for said wheel, clutch-gears on the hub of said wheel adapted to act in opposite directions, a slotted plate or bar straddling the said hub between the clutclrgears, rack-teeth on diagonally-opposite sides thereof adapted to mesh with the clutch-gears, and a pivoted bar fitted to the opening in the plate D and adapted to move said plate into gear with ont` clutch-gear or the other, and the operating-levers connected with the plate D, the parts being combined, substantially as described.

2. The combination, in a gate having a track resting upon a cogged wheel, A, of the plate or frame D, the gears c c', adapted to the racks of the said frame D, the lever E, shifting cam-plate G, weighted lever F, and projections on the gate, all operating sub stantially as described.

In testimony whereof` I have signgd my name to this specification in the presence of two subscribing witnesses.
